Abstract:

A onedirection rough relations is defined and its structureis depicted which reserves the basic features of Srough sets. The subblocks by divide relation are used to substitute the equivalent class of rough sets.The article designs a formalized arithmetic to realize the numeric signature and authentication on data communication.

Key words: rough relations; structure; security of data communication
